protected void subscribeActual(SingleObserver<? super R> observer)

Implements abstract io.reactivex.Single.subscribeActual.

Doc from io.reactivex.Single.subscribeActual.

Implement this method in subclasses to handle the incoming SingleObservers.

There is no need to call any of the plugin hooks on the current Single instance or the SingleObserver; all hooks and basic safeguards have been applied by subscribe(SingleObserver) before this method gets called.

Parameters
observer:SingleObserver<? super R>

the SingleObserver to handle, not null

Method Summary

Modifier and TypeMethod and Description
public void
dispose()

Implements io.reactivex.disposables.Disposable.dispose.

Dispose the resource, the operation should be idempotent.

e
)

Implements io.reactivex.Observer.onError.

Notifies the Observer that the Observable has experienced an error condition.
public void
onNext(T

value
)

Implements io.reactivex.Observer.onNext.

Provides the Observer with a new item to observe.
public void
onSubscribe(Disposable
the Disposable instance whose Disposable#dispose() can be called anytime to cancel the connection
d
)

Implements io.reactivex.Observer.onSubscribe.

Provides the Observer with the means of cancelling (disposing) the connection (channel) with the Observable in both synchronous (from within onNext(Object)) and asynchronous manner.

public void onError(Throwable e)

Implements io.reactivex.Observer.onError.

Doc from io.reactivex.Observer.onError.

Notifies the Observer that the Observable has experienced an error condition.

public void onNext(T value)

Implements io.reactivex.Observer.onNext.

Doc from io.reactivex.Observer.onNext.

Provides the Observer with a new item to observe.

The Observable may call this method 0 or more times.

The Observable will not call this method again after it calls either onComplete or onError.

Parameters
value:T
